ImmunoGen, a biotechnology company that develops novel anticancer therapeutics using its antibody-drug conjugate (ADC) technology, has again been named one of The Boston Globe’s Top Places to Work.

The Boston Globe’s 2013 Top Places to Work survey, conducted by WorkplaceDynamics, measured responses of employees from numerous organizations in Massachusetts to statements regarding six key factors related to employee happiness, including company direction, execution, employee connection, work load and responsibility, management and pay and benefits. More than 76,000 individuals responded to the survey. Among survey respondents, greatest importance was placed on aspects related to employee appreciation and feeling that their work is meaningful. WorkplaceDynamics also found that, of all the cities surveyed, employees in the Boston area were most enthusiastic about their companies, making Boston the top of the Top Places to Work.

Daniel Junius, president and CEO, said, “ImmunoGen is focused on developing and advancing meaningful new treatments for cancer. To succeed in this mission, it is essential that we hire and retain top quality people. We are extremely pleased that our supportive culture and other key aspects of working at ImmunoGen are reflected in the survey responses and that our company has again been recognized as one of The Boston Globe’s Top Places to Work.”
